(CNN) – Two children in Colorado were injured when a bounce house went airborne while they were inside.
Parents and players watched helplessly as a strong gust of wind blew the inflatable slide across a field and into the middle of a Colorado lacrosse tournament..
“We thought the girls were going to get taken out cause this thing’s massive,” one witness said. “As the wind picked up, it would tumble. Like a bag in the wind.”
“All of a sudden, it picks up and there’s a girl going down the slide. She flies out about eight feet in the air,” another witness said.
A 10-year-old girl was thrown from the bounce house right away, but an 11-year-old boy continued to tumble another 200 to 300 feet before the slide finally came to a stop. Both are recovering from minor injuries.
Airbound — the company operating the bouncy slide — says it maintained all safety precautions including having their staffing on site.
“We did have the inflatable properly staked to the ground,” the company said in a statement. “We do wish that we had been able to foresee the microburst wind and shut the ride down prior to this incident occurring.”
“In no way, shape or form were we trying to operate that ride in those winds,” the company added.
This isn’t the first time these party favorites have gone airborne.
Just last month — three children playing inside a bouncy house in upstate New York were sent flying nearly two stories high when the inflatable structure was blown right off the front yard.
In 2011, 13 people were injured when another bouncy house was swept into a crowd of onlookers at a soccer game in Long Island.
That same year, another accident was caught on camera at a fifth grade graduation party in Tucson, Arizona.
